The CS gas lets you know if you have a good seal with your mask. Removing the mask and singing the hymn is purely for "motivational" purposes. As I stated earlier, CS is a nonlethal agent, so "handling" it is pointless beyond its effect as a training aid. Learning how to get a proper seal so you can survive lethal agents in combat is the sole reason for the training. You continue to confuse training aids and methods with the training objective.

You said the strongest woman was only as strong as the weakest man. That's an exact quote. There's an example of the strongest woman. You lose.
You might find a few hormone-laced freaks who can pump iron, run well, look mean and speak with deep voices. But if you dredged up the meanest bulldyke you could find, she would still be dead meat in the infantry. Wishing yourself a man won't make you one...
